水（地）源热泵空调系统测试及能效影响因素分析
Tests for water (ground)-source heat pump system and analysis for factors influencing energy efficiency
摘要：
通过对重庆地区已运行1年以上的5个水（地）源热泵空调系统进行的夏季能效测试，分析了各系统的实际节能特性和运行现状，发现各系统在正常运行状况下的节能效果不明显，采用《测评导则》推荐的评价方法，计算得到各系统的节能率很少达到30%以上。根据测试结果和系统设计资料，分析了各系统主机能效和输配能效水平，探究了系统节能效果不理想的原因，并对影响系统节能效果的因素进行了分析。分析得出，系统负荷率、冷却水进水温度和水泵调节性能等因素分别在不同程度上影响了系统的能效水平。
Abstract：
Through the energy efficiency test in summer for five water (ground)-source heat pump systems which have been running for more than one year in Chongqing area, analyses the actual energy-saving feature and operation situation of each system. The results of energy saving potential are not perfect. Uses the evaluation method recommended by Assessment guideline to compute energy-saving rate of those systems, the results rarely reach to more than 30%. According to the test results and system design data, analyses the host and transporting energy efficiency levels of each system, and inquiries the reasons for unsatisfactory performance. Furthermore, carries out an analysis for factors affecting system energy-saving. The results show that the load rate of the system, inlet temperature of cooling water and adjustment performance of water pump affect the energy efficiency levels of the system to different extents.
